| Research Abstract |
In this study, we developed the experimental sound source which contain rich high frequency components above 100kHz, and also, is excellent at sensibility feeling. Then we developed the presentation system that is able to present the high frequency components without loss. Next, we conducted the experiments using the fundamental brain network activity index. These results suggested that the frequency bands which evoke remarkable positive fundamental brain network activation exist. Conversely, these results suggested the potential exist of the frequency bands which reduce the fundamental brain network activation. Moreover, we extracted the features of artificial high frequency components in the modern urban environment, and suggested that these artificial high frequency components not evoke enough the fundamental brain network activation.
